' VENDING-MACHINE.

Specification of Letters Patent.

Patented May 21, 1918.

Be it known that I, FREDERICK G. SGHEN- KEL, a citizen of the United States, residing at Richardson Park, Wilmington, in the county of New Castle, State of Delaware, have invented a new and useful Vending- Machine, of whichthe following is a speci fication.

My invention relates to improvements in coin controlled vending machines. The object is to provide improved means whereby coins of required denomination are utilized to render efl'ective releasing mechanism for closures, means whereby coins other than that of required denomination cannot be inserted in the device or else are rejected or returned tozthe customer, means whereby the proper coins I after having performed the functions above recited, are released and delivered to a proper receptacle, means whereby the openingof the closure is indicated to the rear of the device so that the attendant may know when the contents of any vending compart- Inent have been removed so that he may replenish the same and means whereby he may close the compartment subthe locking position by spring 17. This simultaneously ject to the coin opening operation and also to indicate that the compartment is provided with its supply. The invention also comprises improvement in details of construction.

Referring to the drawings, which illustrate merely by way of example suitable means for the embodiment of my invention:

Figure 1 is a sectional elevation showing the coin controlled latching mechanism and coin releasing and door operating mechanism.

Fig of'the latching and releasing mechanism.

Fig. 3 is a vertical section on line 3-3 of Fig. 2.

Fig. 4 is a horizontal section on line 4-4 of Fig. 2.

Fig. 5 is a plan view on reduced scale of the door or closure.

Fig. 6 is a sectional view on reduced scale showing. modifications of the closure c'onstruction.

' Fig. 7 is an elevation of the coin slot device.

Fig. 8 is an elevation on reduced scale 2 is a similar view on enlarged scale thickness of the coin. connected by the link 26 to the lever 27 p1vshowing the arrangement of a plurality of vending compartments.

Similar numerals refer to similar parts throughout the several views.

A suitable compartment is provided for containing the object or objects to be sold, for example, a sandwich and a cup of coffee. The receptacle or compartment is accessible upon one side for example, the rear, to the atendant who replenishes the supply from time to time as required. This compartment is also accessible upon the other side, forexample the front, to the customer I who desires to purchase the contents thereof, but it is not accessible to the customer,

until he has performed certain predetermined requirements. This is secured by door or closure 10 which is adapted to cover the front opening of the compartment. This door is slida ly mounted on the rollers 11, or other suitable means, and is normally actuated or moved into the open position by. the weight 12 secured to cord 13,-which cord '13 is secured to the door 10 and moves over the roller or pulley 14. The door 10 is provided with the pin 15 adapted to engage with the latch or detent 16, moved into at 25. It will be noted that these two mem-.

bers 23 and 24 form a channel which will just accommodate the desired number of coins of desired denominationin the present example, three nickels. The upper concave portion of the latch 16 normally forms a stop for the lowest nickel. It'will be understood that the walls 21 and 22 are spaced apart a distance slightly greater than the at 28, andat its upper end pivotally connected to the bar 29 slidably mounted on the pins or rollers 30 projecting into slot 31. The end of bar 29 is adapted to abut against door 10, when-the door-1s in the closed position. This serves to mamtain lever 27 in the position shown in Fig. 2, against the tension of spring 32. The lever otally mounted The member 24 is 33 is provided with a free end adapted to engage the top of the uppermost coin. This lever is actuated by the handle 34 connected with the spindle projecting from lever 33 through the front wall 34 of the casing. Lever 33 has a counterbalance 35 and a stop 38 for limiting its counterbalanced actuation. A chute is provided for delivering the coins from the front of the panel or casing wall 34, to the channel 37 formed between the walls 21 and 22 and the members 23 and 24. This chute is provided with an opening 38 of size suitable for the required coin.

The lower inclined wall 39 is slotted or cut away, as to part of its extension, leaving narrow marginal edges only which will support the required coin, for example, a nickel,

but will not support a cent or a dime, but

will permit the same to drop through, guided by the apron 40 to the cup ii.

In operation- When the required number of coins of required value have been inserted through the slot 38, and have assumed the position in channel 3'? as shown in Fig. 2, the hand lever 34: is actuated causing the depression of the free end of lever 33 to engage the top of the three coins and push the same downwardly to actuate the latch 16 against the tension of spring 17, depressing the latch so as to disengage the pin 15 on the door 10, whereupon the door 10, responding to the actuation of the weight 12, moves into the open position, or away from the front of, the compartment, which it has normally closed. Upon the movement of the door or closure to the open position and away from the end of bar 29, bar 29 is permitted to move to the right in response to the actuation of spring 32 pressing against lever 2?. This carries the lower end of lever 24 to the left which opens the lower end of channel 37 sufficiently to permit the coins to drop into receptacle 42".

When the customer opens the compartment in the manner above described, the attention of the attendant should becalled to the same in some suitable way. in Fig. 5 is shown the door 10 connected with another door or movable member 42, by an arm 43 or other suitable means, so that when door 10 moves to the open position, the member 42 moves to a corresponding position. After the attendant has replenished the compartment, the member 42 may be moved into the closing position which simultaneously moves door 10 into the closing position and into engagement with latch member 16, ready for the next opening operation. Door 10 is preferably provided with a glass panel 44, so that the customer may inspect the conmes es tents of the compartment. In Fig. 6 an alternative arrangement is shown, in which the door 10 is provided with a pm 52 WlllCll actuates a lever a5 on rod 46 which is consharp peripheral edge of the coin. The wall of the casing overlying the coin guideway may be provided with a transparent panel as of glass, as indicated at 51, in order that the-coins may be inspected, when in the position shown in Fig. 2.

What I claim is 1. In combination. with a container, a

movable closure therefor, a, detent for the closure, means for actuating the detent including a manually operated lever, adapted to communicate movement from the lever through a coin or coins'to the detent, and means forming a guide-way for the com or coins, said guide-way forming means including a movable member controlled by the closure.

' 2. In combination with a container, a movable closure therefor, a detent for the closure, means for actuating the detent including a manually operated lever, adapted to communicate movement from lever through a coin or coins to the detent, and means forming a guide-Way for the coin or coins, said guide-Way forming means including a movable member controlled by the closure and adapted to release the coin after the actuation of the detent.

3. The combination of a container, a slid-' ably movable door therefor, door actuator, a latch for restraining said actuator, a lover for actuating the latch, means providing a guide-Way for a predetermined arrangement of coins to establish operative relationship between lever and latch, said guide-way meansincluding a member forming part of the guide-Way operated to release the coin when the door is moved.

4:. The combination of a container, a door.
